y To all whom 'it nog concern la citizen oi the United States, residing at Grant, in the county of Choctaw and State "of Oklahoma,Y have invented new and useful improvements in flDernount-able Rims, of

, which the following is a specication.

. This invention relates to improvements f in demountable rims for automobile wheels icy.

sion of a vfis and contemplates in particular fthe provirim having a locking ring establishing connectionl with the rim through a bayonet joint connection and frneans for f looking the ring in position.

One forni of the invention is illustrated in the accompanying' drawings described 1n thaspecification below and the novel fea- -="t1 1res are broadly set orthin the claims.

In tliejdravvings:

Figure l represents -a fragmentary side elevation of an automobile Wheel having the riin comprising the present invention applied thereto and showing a tire in position on the rim, Y

saine,

Fig. Q is a transverse sectional view of the Fig. S- is a fragmentary perspective vievv illustrating in detail b ayonefjolnt connec- `tions between the locking ner rim,

Fig. 4 shows the locking pin in detail. ln the drawings lfliave designated by the numeral 1an automobile Wheel which may be of any customary construction fand in the present instance has a `Wooden folly 2 connected to a hub i-by spokes 4, Suitably secured on the telly by bolts 5 or in any other acceptable manner is a metallic rim 6 having adjacent one edge a radially disposedllange or lshoulder 7 which may have the inner face beveled or sloping' as shown at 8 for` receiving one side or the usual outerVtire-*holding rim 9. vThe inner rim is provided in periphery toward the other edge with a plurality of spiral chantraa. The eine@ n may be fOr-med when' desired with a plurality oirefnsses. snoepen- 'ings-l for engagement by a snilliile tool ring and the in-` whereby the ring may be tightly screwed in position or unscrevved. For retaining the ring l2 in the operative position it is provided in the lateral outer surface with a plurality of recesses adapted for receiving the inwardly bent end l@ of a locking pin i7 slidably and rotatably inserted in an opening 18 Wherevvith the telly is formed transversely. llhe other end or' the pin 17 is provided with a head 19 which may be screwv threaded or otherwise detachably secured on the pin. and the adjacent end of the opening 18 is suitably counter-bored for receiving a compression spring 20 bearing against the bottom of the counter-bore and the head 19 to maintain the bent end 16 of the pin 17 in the engaged position. SuitJ able means shown as a ring 21 constituting an integral part of the bent end of the pin are provided whereby the pin may be man- -ually moved longitudinally to disengage the pin end 16 from the recess l5 and may be rotated to remove the bent end out of the path of the ring to permit removing the ring.

' The herein described embodiment of the `invention while constituting the form which is beived to be preferable represents only one of many possible modifications of the invention and the right is reserved to all such variations and departures therefrom as fall 'Within the scope of the invention as 'indicated by the latitude off the claims.

What l lclaim is y l. ln a demountable rim structure for vehicle Wheels, the combination of the telly formed with an opening, the shouldered inner rim on the folly, the outer rim detachably mountedV on the inner rim, the locking ring adapted for bayonet joint connection to the inner rim and provided in the laterally outer surface With recesses,

and the spring pressed locking'pin slidably mounted in the opening or the f elly and provided With a hooked end forengaging in the recesses or said locking ring.

2. ln a lc lemountable rim structure for vehicle wheels7 a ielly i'ormed transversely with a countenbored opening, a shouldered inner rim on the telly, said riin formed with bayonet grooves, an outer rim loosely mounted on the inner rim, a locking ring provided Withlugs 'for engaging in the baycnet groovesof the inner rim and provided in the laterally outer surface vvitb. a plu? @2J Y ifneaiei der adapted for clamping said oute rim against said shoulder of the inner rim, a headed pin loosely insertedin Said opening of the telly-a spring in the counter-bore of' said opemng and bearing against the head of the ping-Said pin formed' at the other end with the bent poi'tion` for engaging' in said recesses of the ring to prevent rotative movement .of the `fini, the last mentioned l0 end of the pin having a portionadanted to portion out of the Way otlie ring to pemnit 15 removing. the ring. i a v *in testlmony whereof l mx my signatu'e.
